Patent DE-3113667-A1 (DE)
Title: Method for determining the position of moving objects, particularly vehicles, and arrangement for carrying out the method
IPC: G01S13/78
Filed: 1981-04-04
Abstract: Each object is surrounded by at least four stations constructed as receiving and/or evaluating station, in such a manner that their connecting lines form an oblique-angled polygon. The evaluating station cyclically interrogates the objects located in the polygon in an addressed manner. Each object sends out an addressed identification signal, the Doppler shift of which is detected by the receiving stations and evaluated by the evaluating station. The Doppler shift in each case determined is corrected by the theoretical Doppler shift detectable by each receiving station, which is assumed by the object due to its own speed with respect to a station located directly on its longitudinal axis. After that, the coordinates of the respective object are determined from the reference Doppler frequency thus determined. Each object exhibits an electronic signal transmitting device which is operated by a control pulse of the evaluating station. The signals of the signal transmitting devices are converted into electronic signal processing devices of the receiving stations and received in the electronic signal evaluating device of the evaluating station and converted for determining the position of the object. <IMAGE>

Patent DE-3118760-A1 (DE)
Title: Coin-operated gaming machine designed as table-top machine
Inventor: GAUSELMANN PAUL
IPC: A63F5/04
Filed: 1981-05-12
Abstract: The coin-operated gaming machine, designed as a table-top machine, has a plurality of playing positions, preferably two opposite playing positions. Win symbols specific to individual playing positions, on rollers arranged adjacently on a common axis, can be seen through windows which form window arrangements specific to individual playing positions and mutually offset peripherally and axially. The central roller bears a sequence of win symbols for each playing position, so that, because of rigid allocation and suitable placing of the win symbols, maximum wins can never be simultaneously achieved at both playing positions. A more uniformly distributed win pay-out permits pay-out banks with reduced coin capacity. <IMAGE>

Patent DE-3127766-A1 (DE)
Inventor: STWIOROK ANDREAS
IPC: F02D13/02
Filed: 1981-07-14
Abstract: A device for the angular adjustment of a camshaft of a combustion engine according to speed and load conditions and to the angular position of the camshaft with respect to a driving wheel being controlled by an adjustable mechanism. The technical problem is the angular adjustment of the single or multiple camshafts with respect to the crankshaft according to speed and load conditions. Tooth pulses, or counting pulses, corresponding to the angular position of the crankshaft (2) and reference pulses corresponding to a particular angular reference position (singular tooth) are generated by a transducer, or pulse generator, controlled by the toothed ring associated with the crankshaft and the ignition circuit (13). An address counter (10) is reset by the reference pulses and incremented by the tooth pulses so that the output of the counter provides digital address signals corresponding to the actual angular position of the crankshaft (2). The output signals of the address counter and digital signals corresponding to load conditions are input to a correction processor with memory, (20) the output of which provides a camshaft adjustment signal. During pre-set engine operational periods, a buffer memory ( 21), controlled by the tooth-pulse time base signal, stores an adjustment signal used as a camshaft correcting variable, which is then delayed under asynchronous clocking and fed into an electromechanical control device (FIG. 3) which effects a rotary-then-linear displacement of a control member (31) and subsequently an angular corresponding displacement of the camshaft(s) to the correcting variable.
